CIMSS records Puyehue-Cordon Caulle volcanic eruption in Chile
Posted by JAC on 6/6/2011, 6:59 am


An explosive eruption of the Puyehue-Cordón Caulle volcano in Chile occurred on 04 June 2011. GOES-12 0.65 m visible channel images (above) showed a darker gray ash cloud punching above the meteorological cloud deck around 18:15 UTC, with the ash cloud quickly spreading southeastward and moving over Bariloche, Argentina (station identifier SAZS).

A comparison of GOES-12 3.9 m shortwave IR and 10.7 m IR window channel images (below) revealed a pronounced and persistent "hot spot" signature (dark black pixels) at the summit of the volcano on the shortwave IR images - while the long and narrow cold high-altitude volcanic cloud (exhibiting IR brightness temperatures around -60 C, darker red color enhancement) could be seen spreading southeastward for a great distance on the IR window images.





CIMSS activities in the GOES-R Proving Ground include the generation of real-time volcanic ash retrieval products (using Meteosat SEVIRI data as a proxy for GOES-R data), which showed a significant volcanic ash plume emerging over the Atlantic Ocean (below).
